Abstract To evaluate the value of apnoea + hypopnoea index versus self-reported sleepiness at the wheel in anticipating the risk of sleepiness-related accidents in patients referred for obstructive sleep apnoea. A cross-sectional analysis of the French national obstructive sleep apnoea registry. 58,815 subjects referred for a suspicion of obstructive sleep apnoea were investigated by specific items addressing sleepiness at the wheel and sleepiness-related accidents. Apnoea + hypopnoea index was evaluated with a respiratory polygraphy or full polysomnography. Subjects had a median age of 55.6 years [45.3; 64.6], 65% were men, with a median apnoea + hypopnoea index of 22 [8; 39] events/h. Median Epworth sleepiness scale score was 9 [6; 13], 35% of the patients reported sleepiness at the wheel (n = 20,310), 8% (n = 4,588) reported a near-miss accident and 2% (n = 1,313) reported a sleepiness-related accident. Patients reporting sleepiness at the wheel whatever their obstructive sleep apnoea status and severity exhibited a tenfold higher risk of sleepiness-related accidents. In multivariate analysis, other predictors for sleepiness-related accidents were: male gender, ESS, history of previous near-miss accidents, restless leg syndrome/periodic leg movements, complaints of memory dysfunction and nocturnal sweating. Sleep apnoea per se was not an independent contributor. Self-reported sleepiness at the wheel is a better predictor of sleepiness-related traffic accidents than apnoea + hypopnoea index.

Background: The aim of this study was to assess the prevalence of Obstructive sleep apnoea syndrome (OSAS) in long-distance drivers located in the Zonguldak area and to show the correlation between OSAS and traffic accidents. Methods: In this study, 241 long-distance drivers who were residents of Zonguldak province were interviewed face-to-face and a questionnaire regarding OSAS symptoms, occupational histories, and numbers of accidents was administered. Body mass measurements were also taken from participants. Patients who exhibited evidence of OSAS underwent polysomnography (PSG). Results: Snoring was detected in 56% out of all participants, daytime sleepiness was observed in 26.6% and apnoea in 11.6%. All-night PSG was applied to 42 participants who had a high probability of clinical OSAS. Among these, eight had an apnoea-hypopnoea index (AHI) < 5. The prevalence of OSAS was 14.1%. There was a significant relationship between the ratio of traffic accidents per professional years and AHI (r = 0.571; p < 0.005). Conclusions: OSAS prevalence was higher among long-distance drivers in the Zonguldak region. Disease severity was directly proportional to traffic-accident risk, and thus represents a serious social problem.

Abstract Background There is a high prevalence of anxiety in patients with obstructive sleep apnoea and such patients often describe fatigue in addition to sleepiness. We currently use the Epworth Sleepiness Scale (ESS) to quantify sleepiness in our patients, but we do not have useful tools for assessing fatigue. Fatigue is a common symptom in patients with many medical conditions but has not been well studied in patients presenting to sleep services. Our hypothesis is that patients with obstructive sleep apnoea who have a comorbid anxiety disorder, as measured by the Hospital Anxiety and Depression Scale (HADS) are likely to have increased symptom burden such as fatigue or poorer functional outcomes of sleep. Methods Analysis of prospectively collected data from 128 adult patients referred for suspected obstructive sleep apnea to Monash University Health Sleep Clinic. All patients have completed a comprehensive questionnaire prior to their first clinical review assessing their symptom burden at baseline. Questionnaires completed include extensive symptom and medical history assessment, the Fatigue Severity Scale (FSS), ESS, HADS, Functional Outcomes of Sleep Questionnaire (FOSQ), Insomnia Severity Index (ISI) and Global Fatigue Score. All patients were subsequently reviewed by a clinician and have overnight polysomnography data available. Progress to date; Data collected for all 128 participants. Preliminary analysis currently underway. Intended outcome & impact; We intend to examine whether the comorbidity of anxiety results in an increased or different symptom burden in patients referred for suspected obstructive sleep apnoea when compared to patients without a history of anxiety.

Abstract Background Obstructive Sleep Apnoea (OSA), a condition characterized by a complete or partial cessation of airflow during sleep, can cause various cardiovascular disorders including hypertension. The aim of the study was to determine the prevalence of OSA in patients with hypertension. Methods A cross-sectional prospective cohort study of 504 patients with hypertension was undertaken at a tertiary care hospital of India for a period of 6 months. OSA was evaluated using the Berlin questionnaire while the daytime sleepiness was determined using Epworth Sleepiness Scale. Data analysis was done using SPSS v. 20. Results High risk of OSA was identified in 120 (23.8%) patients and the prevalence of sleepiness (Epworth Sleepiness score >16) was found to be 32.5% (95% CI, p < 0.001) in these patients. The mean neck circumference, waist circumference and waist-to-hip ratio for high-risk OSA group were 37.41 ± 3.396 cm, 105.90 ± 11.28 cm and 1.01 ± 0.065 respectively while for the low-risk group, these parameters were 35.45 ± 2.652 cm, 98.75 ± 10.87 cm and 0.99 ± 0.080 respectively (95% CI, p<0.001). The mean blood pressure (BP) ≥133.52/84.37 mmHg was recorded in patients with a high risk of OSA (95% CI, P < 0.05), and resistant hypertension (3.3%) was significantly associated with the risk of OSA (95% CI, P < 0.05). Conclusion In the tertiary health care setting, the prevalence of high-risk of OSA in patients with hypertension is high. Screening for OSA should be a part of the hypertensive medical investigation and patients may benefit from a proper evaluation of OSA.

Obstructive sleep apnoea (OSA) is associated with a rise in cardiovascular risk in which increased sympathetic activity and depressed baroreceptor reflex sensitivity (BRS) have been proposed. We examined this association in a sample of healthy elderly subjects with unrecognised OSA.801 healthy elderly (aged ≥65 years) subjects undergoing clinical, respiratory polygraphy and vascular assessment were examined. According to the apnoea–hypopnoea index (AHI), the subjects were stratified into no OSA, mild–moderate OSA and severe OSA cases.OSA was present in 62% of the sample, 62% being mild–moderate and 38% severe. No differences were found for BRS value according to sex and OSA severity. 54% of the group had normal BRS value, 36% mild impairment and 10% severe dysfunction. BRS was negatively associated with body mass index (p=0.006), 24-h systolic (p=0.001) and diastolic pressure (p=0.001), and oxygen desaturation index (ODI) (p=0.03). Regression analyses revealed that subjects with lower BRS were those with hypertension (OR 0.41, 95% CI 0.24–0.81; p=0.002) and overweight (OR 0.42, 95% CI 0.25–0.81; p=0.008), without the effect of AHI and ODI.In the healthy elderly, the presence of a severe BRS dysfunction affects a small amount of severe cases without effect on snorers and mild OSA. Hypertension and obesity seem to play a great role in BRS impairment.

Background: Obstructive Sleep Apnoea (OSA) has been too common yet under diagnosed clinical entity. It is associated with the metabolic syndrome, a cluster of cardio-metabolic parameters including central obesity, insulin resistance, hypertension and dyslipidemia. Obesity predisposes to both OSA and disorders in glucose metabolism. There is growing evidence that OSA confers an independent risk of adverse glucose metabolism.Methods: The present study conducted in the Department of Medicine at MDM Hospital attached to Dr. S.N. Medical College, Jodhpur, Rajasthan, India. Participants after understanding the study protocol and procedure, asked to give their written consent for the study. It was a cross sectional hospital based study in patients, screened at Diabetic clinic and those referred from the periphery. Berlin questionnaires and Epworth score are tools to screen for OSA attending the Medicine OPD and IPD, Dr. S. N. Medical College, Jodhpur. 50 patients with type 2 DM and 20 age and sex-matched controls were studied. Randomly selected T2DM subjects of age 20 to 75 years both sex with obesity, BMI>25 kg/m2, clinical history suggestive of OSA, Epworth score>6, Positive Berlin questionnaires were included in the study. Acute and unstable medical condition e.g. CHF, CRF, COPD, Recent stroke, Acute ACS, Pregnant women were excluded.Results: In the study OSA was prevalent in the diabetic population (54%), Mean age of the study population was 54.96±9.35 years. OSA was found to be increased with increasing age with maximum prevalence in ≥60 year’s age group. OSA was more prevalent in the male population (64.29%), in urban population. Snoring, observed sleep apnoea, restless sleep/insomnia, excessive daytime sleepiness and non-refreshing sleep were significantly associated with OSA. (P<0.001). Prevalence of OSA was more in high BMI group (≥35 kg/m2), OSA increased with increase in neck circumference. OSA was more in subjects with uncontrolled diabetes (blood sugar>200 mg/dl), smokers and alcoholics.Conclusions: This study shows that OSA has a high prevalence in subjects with T2DM and identify several factors that may be associated with its presence in the diabetic population. OSA can be usefully and easily assessed in an outpatient setting by using a portable device such as Apnea Link. Clinicians should increase patients' awareness of the signs and symptoms of OSA and refer for sleep studies when appropriate. Once diagnosed, patients should be encouraged to adhere to CPAP treatment in order to halt progression and prevent complications.
